Google support for GoodRelations
Google have announced support for the GoodRelations vocabulary for product and price information in Web pages, Product properties: GoodRelations and hProduct. This is primarily of interest to ecommerce sites but is more generally interesting because it is likely to lead to a significant rise in the amount of RDF flowing around the Web. It therefore potentially represents a significant step forward for the adoption of the Semantic Web and Linked Data.
Martin Hepp, the inventor of the GoodRelations vocabulary, has written about this development, Semantic SEO for Google with GoodRelations and RDFa, suggesting a slightly modified form of markup which is compatible with that adopted by Google but that is also "understood by ALL RDFa-aware search engines, shopping comparison sites, and mobile services".
